Michael Zehaf-Bibeau, who shot and killed Cpl. Nathan Cirillo at the National War Memorial earlier this week, was asked to leave the B.C. mosque he attended and objected to its policy of allowing in non-Muslims, a B.C. Muslim Association spokesperson has said.

Rashid told reporters Zehaf-Bibeau had attended the mosque for three to four months in 2011 and described him as keeping largely to himself.

But, he said, Zehaf-Bibeau did object to the openness with which the mosque accepts non-Muslims.

"The mosque operates on a foundation of welcome, of community outreach and interfaith dialogue and that cannot take place when we close the doors on our neighbours.

"If he was not OK with that, he should probably choose another mosque to go to and pray."

Finally, Zehaf-Bibeau attempted to sleep at the mosque when he was released from prison in 2012, said Rashid, which led to him being asked to leave.

At Zehaf-Bibeau's bail hearing, he told the judge himself that he wanted to serve time. The judge agreed to detain him over Christmas.

RCMP asks for tips

The RCMP on Friday circulated a mug shot of Zehaf-Bibeau taken by Vancouver police and asked anyone with information about his movements from Oct. 2 onward to contact the security tip line at 1-800-420-5805 or RCMP.NSIN-RISN.GRC@rcmp-grc.gc.ca.

New information also emerged about Zehaf-Bibeau's online presence. A data security expert who works for Public Safety Canada says there is online evidence that Zehaf-Bibeau was radicalized.

"We have indications that he interacted with sites and individuals that have contact to Syria," Rohozinski said in an interview with CBC News on Friday. "We know that his principal channel to radicalization seems to have been with online content."

Rohozinski said SecDev has turned what material it has over to the relevant authorities.
